This is an attempt to fix device hotremove with VFIO.
A soft device hotremove request through sysfs [1] would
currently just block until the SPDK process manually
releases that device - e.g. upon an RPC request.
VFIO won't get unbound from the device untill userspace
releases all its resources. VFIO can signal a pending
hotremove request by kicking any file descriptor provided
by the userspace - and DPDK does provide such descriptor -
but SPDK does not listen on it.
DPDK does offer handy API to listen and in this patch
we make use of it inside our env/pci layer. Within
a DPDK callback we set an internal per-device hotremove
flag, which upper-layer SPDK drivers can poll with a new
env API - spdk_pci_device_is_removed().
The VFIO hotremove event will be sent to primary
processes only, so that's where we listen.
We make use of this new API in the NVMe hotplug poller,
which will process it just like any other supported
hotremove event.

This API had good intentions, but as more complicated
use cases came up where base bdevs could come and go,
we've realized that the bdev layer will need another
mechanism to query bdev modules on these types of
relationships between a virtual bdev and its base
bdevs. We removed all code related to tracking
the array of base bdevs a long time ago.
Change all existing callers to use spdk_bdev_register.
Document spdk_vbdev_register as deprecated for now,
and change its implementation to just call
spdk_bdev_register for simplicity sake.

Historically, all memory returned from spdk_*malloc()
used to be physically contiguous, hence it could be
addressed by offsetting just a single physical address.
Since DPDK dynamic memory management came along, the
above is no longer true. Memory returned from spdk_*malloc()
doesn't have to be physically contiguous anymore. The
phys_addr returned from spdk_*malloc() only applies to
the beginning of the allocated buffer and user can't
possibly know how big that "beginning" is.
The phys_addr parameter in spdk_*malloc() is useless on
its own in most cases and only suggests that the returned
buffer is physically contiguous, which is wrong.
This information can be returned from spdk_vtophys(),
which is the only safe way to retrieve physical addresses.
That's why phys_addr param in spdk_*malloc() is now
deprecated.
